Earthquake and Tsunami Damage to Steel Structures
The 2011 Tohoku-Chiho Taiheiyo-Oki Earthquake (2011 Tohoku earthquake for short) caused widespread damage to steel building structures. The Steel Committee of the Architectural Institute of Japan (AIJ) conducted earthquake damage reconnaissance over cities where severe ground shaking was recorded. In general, steel office and industrial buildings exhibited excellent seismic performance. Buildings that used older cladding installation methods sustained damage to their claddings even if their structural performance was excellent. Damage to a few braced frames offer valuable insight into gusset plate connection design. It is widely recognized that a devastating feature of the Tohoku earthquake is the vast damage over the north-east coast of Japan caused by tsunami. This tsunami claimed nearly 20,000 lives. This coast is a rich fishing area and hence housed many fishing ports and facilities among other major buildings. At the port town of Onagawa, where the tsunami reached an extreme severity and height of 15 meters, a three-story steel building fell sideways after its piles failed. While the majority of steel buildings stood upright after the tsunami subsided, these buildings sustained heavy damage to its external and internal finishes. This paper summarizes findings made by the authors and their AIJ colleagues.
